To all whom t mayrooncern:

Be it known that` I, JOSEPH FEIGENBAUM, a citizen of the United States, residing at 1018 N. Western Ave., Los Angeles, in the Angeles and State'of California, provements in Incinerators,'ofV which the following is a specification.

This invention relates to incinerators, and 2 1o has for an object to provide'an improved.

incinerator builtV of vsections of reinforced concrete composition. AnobjectV is 5to pro-I vide a concrete incinerator of' simplev and substantial construction, and one-'1n which provision is made forexp'ansion vand* contraction of the body 'or vshell toisecure du-` rability and long life.

Other objects and advantages'fwil'l .be'v made manifest in' theffollowing specificay tion of embodiments ofthe invention illustrated in the accompanying drawings, wherein- I f `Figure 1 is a vertical, central 'section through an embodiment 'vof the invention.A

Fig. 2 i's a perspectiveof a portion vof the furnace shell showing a metallic door struc- @ne of thebroad invention is to provide a 'domestic 1nc1n-- eratorf such construction that'vthe fire erator, will be materially reduced and practically owercome,fsince 'the incinerator is largely, resisting material withsmall or no kexterior metal exposureslikely to ignite objects brushing against `the`same whilef'highly:` heated.'

g In Figure 1, the incinerator isfshown as including a-substantially annular concrete compositionbaseor foundation 2, desi ned 5, which may be disposed contiguous to or in the draft opening 4.

The shell or lire box of the incinerator .ments aremade of a have invented newv and useful Im- `structure having purposes of the present of the shell *under heat.' hazarl, made possible by the contact of objects a'gainstthe exterior'of theincin# if ynot whollyi constructed .ofl a' lire" Ywith a hood 18,

which has `a lower,-c`onical1 portion, thebottom of whichvmatches -withfand isi cemented at 15 on the Stop: of "ft-heshell.A {The portion of they domelfl'l isffofflcylindrical form and forms upper the chimney for the furnace. Atftheiupper endy of i the: chimney there is provided-a3 spark arresting screen r16,'whichfis embedded on the top of the chimney b'y-a" crown ring 17, which is vmade vof reinforced' concrete I naterial, as also is the dome 14 with its integral chimney portion 14a. The crown ring 17 is permanently mounted on the topof the chimney portion 14 so as to form la substantially integral part therewith.

The crown ring'l? is formed integrally spaced a suitable distance above thecrown ringv and secured thereto by integral standards 19 which, with the hood, are made of concrete material integral with the crown ring.

There may be provided, in the bottom of the incinerator, a burner 20, of any suitable no .segments Abeing 4provided with 1.

3. An incinerator including a rustoconoidal shell formed ofsegments of monolithic form and having longitudinal, abutting edges, one of the sections being provided with a filling aperture in its side portion, a dome mounted upon the top of the shell, the .dome being provided with an aperture having a movable closure, spark arresting-'means at the top of the dome, a` hood arranged above the spark arrester, and an annular foundation member at the lower portion of the shell, said foundation 'member being provided with a grate structure, and having a draft opening at one side.
